"I have a lot of tattoos. It's true, I do," the 43-year-old actor revealed to ET's Kevin Frazier when asked him about his latest ink, what appears to be a giant phoenix spread across his back. That said, Affleck claims there has not been "a good representation of it in the media" and says there's a reason he hasn't shown the tat off himself.

"I don't have them places where you can see them, because that's private," he says.

Though Affleck didn't expand upon what exactly prompted this tattoo, it did inspire a hilarious moment with his Batman v Superman co-star, Henry Cavill.

Affleck jokes, "He knows. He's seem them all."

To which Cavill quips, "Very small tattoos."

"They make everything else look bigger," the two-time Oscar winner says with a laugh, before concluding, "There's inspiration for all of it, of course. But we'd have to get much, much closer than we are to get any further with it."

Someone who is much closer to Affleck -- his estranged wife and now "good friend," Jennifer Garner -- recently told Vanity Fair of the ink, "You know what we would say in my hometown about that? 'Bless his heart.' A phoenix rising from the ashes. Am I the ashes in this scenario? I take umbrage. I refuse to be the ashes."

The actor, who split from Garner after 10 years last June, has been under incredible public scrutiny over the past year. But he says his work kept him from losing his mind and busting out some of those badass Batman moves in real life.

"I just haven't been tempted! I just have channeled all my energy into this movie," he points out. "This is really exciting for me. It's an honor to be a part of this movie, to be cast in this role and to work with this great cast. I have had such a fun time."

"I've been on both ends of the movie business where you got a movie coming out that you don't want people to go see," Affleck shares. "This is a great one where I have something that I'm really proud of and I really want people to see."

Batman v Superman: Dawn of Justice hits theaters on March 25.

Meanwhile, Affleck adorably revealed that his son, Samuel, thinks he's actually Batman. Check out the sweet story in the video below.
